摘  要：
选用5个不同生态类型春小麦品种为材料,通过大田种植,研究其生长发育和灌浆特性对籽粒产量的影响。结果表明:农麦2号、宁春50号和宁春4号保持了较高的灌浆速率和持续时间,而龙麦33和青春38灌浆峰值出现时间较宁春4号晚,灌浆持续时间短,后期衰减较快,各品种间灌浆速率差异明显;产量方面,农麦2号产量最高,较宁春4号增产11.4%,与龙麦33及青春38间产量差异达到极显著水平。因此,在小麦新品种选育方面宜筛选全生育期适中,灌浆速率较快、灌浆稳定及持续时间长的品种。

摘  要：
Five different ecological types' spring wheat cultivars were selected as materials and planted in the field to study their growth and development as well as the effects of their grain filling characteristics on the grain yield. The results showed that among them, Nongmai No.2, Ningchun No.50 and Ningchun No.4 maintained higher grain filling rate and duration. Compared with Ningchun No.4, the filling peaks of Longmai 33 and Qingchun 38 appeared later, the grain filling duration was shorter, especially in the late period. The differences in the grain filling rate between various varieties were obvious. As for the yield, the yield of Nongmai No.2 was the highest, with an increase of 11.4% compared with that of the control Ningchun No.4. The differences in the yields between Nongmai No.2 and Longmai 33 and Qingchun 38 reached very significant level. Therefore, those with moderate growth period, faster grain filling rate, stable grain filling and long grain filling duration should be selected for breeding new varieties of spring wheat.
